Let me know if you want to play my lvl 83 priest Chin, is so sad it is just standing there still.
Nevertheless regarding your question:
* Paper BP: All stat points into STR, 78 Intell for +9 paper, rest HP
* FP BP: 160 Intell for FP+9, rest on STR
* Chitin and Krowaz BP: 174 or 188 Intell, rest a mix of STR and HP (Usually needs high end jewels and weapon) more like a support/bp priest
Heal/Buff is not worth it, go either Buff/Heal or Duff/Heal, even Heal/Duff is viable
Buff heal: Best build, 70 points in buff, 12 in Master, rest in heal
Duff heal: Best build, 70 points in duff for subside, 60 in heal, rest in master.
Heal Duff: Best build: 75 in heal, 57 in duff for torment, hopefully u can still get 12 in master.
Paper BP: High end 2h clubs: HB+8, II+8 and higher, MS+8 and higher works too, Wirinom +7 is sweet as well, Jewels:Lillimes, Iron set and ROCs
FP BP: HB just for the few STR points remaining, Lillimes, Iron set, ROC's or Leg Bands
Chitin BP: Same as FP bp, but you might have str just for 1h mace like Leonars or Smites, 1h support BP Duff heal is the best in my opinion
Hope it helped, regards
